When you select an element in the model view, the properties for that element appear in the Properties panel in the lower right. The Properties panel allows you to view all the business information associated with the element. The panel will only appear when an element is selected and will disappear when the element is deselected.
Properties
Properties display in groups defined by the engineering application or publisher. These groups can be collapsed by using the collapse icon to hide properties that you do not want to see. Click the expand icon to expand the group to re-display the properties.
If you select a property and then right click, a menu appears allowing you to Find Similar. The Find Similar option finds all related items that have the same class and property value and displays them in the search results tab.
To view properties of assemblies just change the Selection Scope from the control at the bottom right and select the element in the view again.
